Maybe someone swapped out the glovebox door from an early Z/28? Or more likely he bought a Z/28 tire pressure sticker for it at a swap meet and stuck it in the glovebox sometime during the process of turning it into a Z/28 clone. He may forget he did it, but that would be my guess, as it's not even the right style or location of the sticker for when the car was built. Did you check the door jamb for remnants of an F70-14 tire pressure sticker? No reason any small block SS with AC would have ever had 15" tires.
